The Ultimate Jellyfish Aquarium Buying Guide

Thinking about bringing the mesmerizing dance of jellyfish into your home or office? Jellyfish tanks are unique and beautiful pets. This guide will help you choose the right one.

Key Features to Look For

When shopping for a jellyfish aquarium, several features make the difference between a thriving habitat and a frustrating setup. Look closely at these points:

1. Tank Shape and Flow System

Kreisel or Circular Flow: This is the most important feature. Jellyfish need gentle, continuous circular water movement to keep them suspended and feeding. Square tanks often create “dead spots” where jellyfish get stuck or damaged. Look for tanks designed with a smooth, rounded flow pattern (often called a Kreisel system).
Bubble Column: Some smaller desktop units use a central bubble column for circulation. These are often easier to set up but might not be suitable for larger or more delicate species long-term.

2. Filtration and Water Quality

Integrated Filtration: Good tanks have built-in mechanical and biological filtration. This keeps the water clean without needing strong pumps that could harm the jellies.
Protein Skimmer (For Larger Tanks): Advanced setups might include a protein skimmer. This removes organic waste before it breaks down, keeping water parameters stable.

3. Lighting

Adjustable LED Lighting: Colorful lighting enhances the jellyfish’s natural glow. Ensure the lights are dimmable and offer various color options. Bright, direct light can stress jellyfish.

4. Size and Placement

Desktop vs. Floor Unit: Small, 3-5 gallon tanks are great for tiny “moon jellies” on a desk. Larger units (10+ gallons) offer more stability but require more space and stronger flow systems.

Important Materials and Construction

The materials used directly affect the safety and longevity of your tank.

Acrylic vs. Glass

Acrylic: Most jellyfish tanks use high-quality acrylic. It is lightweight and less likely to shatter than glass. However, acrylic scratches easily when cleaning.
Silicone Seals: Check that all seams are sealed tightly with aquarium-safe silicone. Leaks are a nightmare!

Pump Quality

The pump drives the entire system. Look for quiet, low-vibration pumps. A noisy pump ruins the relaxing ambiance jellyfish tanks provide. High-quality pumps also resist calcium buildup.

Factors That Improve or Reduce Quality

Improving Quality:

Quiet Operation: A silent pump and flow system greatly improve the user experience.
Easy Access: Look for lids or access ports that let you feed the jellies and clean the tank without disturbing the main water column too much.
Stable Temperature: While many beginner jellyfish (like Moon Jellies) tolerate room temperature, a tank that allows for a small, submersible heater/chiller provides maximum stability.

Reducing Quality:

Sharp Edges or Internal Obstructions: Any sharp plastic or internal tubing edges can tear the delicate bells of the jellyfish.
Strong, Direct Water Jets: If the pump pushes water too hard or creates turbulent spots, the jellyfish will suffer damage.
Poor Circulation: If the water doesn’t move smoothly in a circle, the jellies will sink or get trapped, leading to poor health.

User Experience and Use Cases

Jellyfish tanks offer a unique way to enjoy aquatic life. They are often chosen for specific environments.

Use Cases:

Stress Relief: Many people use these tanks as “living art” in offices or bedrooms. Watching the slow, rhythmic pulsing is very calming.
Educational Tool: They make fantastic, captivating displays in classrooms or waiting rooms.
Beginner Pet: Desktop Moon Jelly setups are relatively easy to maintain once established, making them a good entry point into specialized aquatics.

User Tip: Remember, buying the tank is only the first step. You must commit to regular water changes and precise feeding schedules to ensure a good experience.

10 Frequently Asked Questions (FAQ) About Jellyfish Aquariums

Q: Can I keep fish and jellyfish together?

A: No. Fish produce waste too quickly and often try to eat the jellyfish tentacles. Jellyfish require very specific, clean water conditions that fish disrupt.

Q: How often do I need to feed my jellyfish?

A: Most common species, like Moon Jellies, eat specialized liquid food once or twice a day. Do not overfeed; leftover food pollutes the water quickly.

Q: How long do captive jellyfish live?

A: In a well-maintained aquarium, Moon Jellies can live for several years. Some species live much shorter lives.

Q: Do I need a special filter?

A: Yes. Standard fish filters are too harsh. Jellyfish tanks require gentle mechanical filtration integrated into the tank design to avoid sucking up the jellies.

Q: What is the easiest type of jellyfish to keep?

A: The Moon Jellyfish (*Aurelia aurita*) is the most popular and forgiving species for beginners.

Q: Can I use tap water directly?

A: Absolutely not. You must use reverse osmosis (RO) or distilled water mixed with marine salt specifically designed for saltwater aquariums.

Q: How do I clean the tank without harming the jellies?

A: You should never remove all the water at once. Use a turkey baster or soft siphon to gently vacuum debris from the bottom, and use soft cloths or sponges (never abrasive pads) on the acrylic walls.

Q: Why are my jellyfish stuck at the bottom?

A: This usually means the water flow is too weak, or there is debris blocking the circulation. Check your pump and clean out any settled food particles.

Q: Do jellyfish need a heater?

A: Moon Jellies prefer cooler water, usually between 64°F and 72°F (18°C to 22°C). If your room temperature is stable, you might not need one, but they dislike sudden temperature swings.

Q: How much does a good starter jellyfish tank cost?

A: Basic, small desktop tanks start around $100 to $200. Larger, more sophisticated systems with advanced filtration can cost several hundred dollars.
